Before I begin my post on Week 11, I just wanted to state that the video Danny created was very informative, anybody reading this that doesn't understand Big-Oh MUST watch it, it takes you through the entire process of a big-Oh proof and should be watched repetitively until the Big-Oh concept sinks in! The link is below:

At any rate, the topic spoken about this week was extremely confusing to me, being of floating-point numbers. At first I understood what Danny meant with base 2, # of digits allowed, exponents running from [-2, 3], etc. However, when the talk of radix point, adjacent numbers and the number list came, I became surprisingly lost in every possible way! From the point of the number list and onwards I hadn't much of any clue of what was being taught, except for the relative error formula. I understand that I must seek help immediately and I plan to do so with the last office hour placed in our final week (Week 12).

There's a movie? Where? I didn't know that... it could be useful in understanding, though I guess after this most recent test, we've all become experts in big-Oh :P
ReplyDeleteThe movie is provided in the link above.
ReplyDeleteHopefully everyone is comfortable with big-Oh, but I've been hearing a couple of people complain about how difficult the last question was, though it was quite similar to one of the assignment 3 questions, where the solutions were posted before the test. =)
